Human factors in drug safety: when wings fall

The safety of injectable medications remains a major patient safety concern, despite advances in human factors. Intravenous medication errors are primarily linked to systemic failures: lack of standardization, illegible labeling, unrealistic procedures, and excessive reliance on individual vigilance. The approaches recommended by the ANSM (French National Agency for Medicines and Health Products Safety), the SFAR (French Society of Anesthesia and Intensive Care), and the SFPC (French Society of Clinical Pharmacy) emphasize the importance of safe system design, standardized practices, and the use of ready-to-administer medications. Integrating human factors allows for a lasting reduction in risks, serious adverse events, and medico-legal impacts.

The safety of injectable medications—particularly intravenous administration—remains a high-risk area in healthcare, despite advances in human factors and ergonomics. This article highlights how poorly designed systems maintain persistent hazards, and why a systems approach must go beyond mere calls for vigilance.

1. The Paradox of Safety—Progress vs. Real-World Practice

In many high-risk fields (aviation, nuclear), the principles of human factors have transformed safety. The healthcare sector has adopted some of these approaches (checklists, a culture of feedback), but the practice of injectable medication remains a structural weakness — particularly in anesthesia, emergency care, intensive care, and pediatrics.

2. Medication Errors: Systemic Causes

Intravenous medication errors are not simply individual mistakes—they reflect systems where:

  • packaging is similar,
  • concentrations vary,
  • preparation devices are poorly standardized.

Human factors show that vigilance alone is not enough: system design must reduce opportunities for error.

3. Standardization and Good Professional Practices

Standardization of practices—in the choice of products, concentrations, labeling, and procedures—is a major lever but still insufficiently applied.
Learned societies such as the French Society of Anesthesia and Intensive Care (SFAR) and the French Society of Clinical Pharmacy (SFPC) produce professional recommendations that help structure this standardization.

📌 SFPC (French Society of Clinical Pharmacy) — recommendations in clinical pharmacy and medication safety: https://www.sfpc.eu

These resources offer methodological guides, training, and expert consensus to structure practice and reduce dangerous variations.

4. The Myth of Vigilance

Traditional approaches in healthcare settings still too often rely on messages like "be more vigilant." In human factors theories, this type of injunction does not correct the root causes: cognitive load, interruptions, fatigue, and organizational constraints make error statistically inevitable if the system has not been designed to prevent it.

5. Ready-to-Administer and Error Reduction

A key solution identified in several international studies is the use of ready-to-administer (Ready-to-Administer) medications, industrially prepared to reduce risky preparation steps.
Data suggest that these solutions:

  • significantly reduce errors,
  • reduce infections,
  • lighten the workload of healthcare professionals,
  • can reduce overall error-related costs.

This type of systemic approach is central to the best practice recommendations promoted by the SFAR and the SFPC in their publications.

6. Theory vs. Prescribed Practice

Many written procedures do not reflect what happens in daily practice. There is a significant gap between prescribed work and actual work, which encourages normal and human, but dangerous, workarounds. A transformation of procedures, taking into account the real constraints on the ground and ergonomic principles, is essential.

7. Towards a Cultural Revolution

This article argues for a cultural revolution in drug safety:

  • integrate human factors principles into system design;
  • strengthen the standardization of practices;
  • promote off-the-shelf devices;
  • value robust professional recommendations.

This transformation is not based on blaming healthcare professionals, but on improving systems—where the real opportunities for error reduction and improved patient safety lie.
